Description

  The present invention is a bento side dish container and a lunch box suitable for packaging and selling vegetable salad, vegetable stir-fry and boiled vegetables such as vegetable juice and water (hereinafter collectively referred to as liquid juice). Concerning the container.

In recent years, due to changes in eating habits, various bento boxes have been sold at bento specialty stores, supermarkets and convenience stores. Various devices have also been made for the lunch box used when packaging and selling the lunch box depending on the type of lunch box to be sold and how to use it.

For example, Patent Document 1 discloses a packaging container in which a plurality of container bodies are vertically stacked in a heavy box shape, and a lid is provided on the top thereof, and the upper container body is covered with the lid, and the lid A multi-layered container configured to fit and hold the peripheral flange part of the body to the peripheral flange part of the lower container body, and the packaging with improved sealing performance by fitting and holding the lid and container on the outer periphery respectively. A container is described.

The packaging container has been devised to cope with various ingredients used in the lunch box and the amount of the ingredients. However, it is easy to get liquid juice in the lunch box, such as vegetable salad, stir-fried vegetables, and various boiled foods. The following problems have arisen when side dishes are stored and packaged.

If a container with a lot of juice is stored and packed in a conventional lunch box container, when the consumer (buyer) carries the lunch box, the liquid juice from the dish crosses the partition wall of the lunch box, It has the problem that it adheres to other side dishes and the flavor of the ingredients is impaired. In addition, although the above-mentioned conventional lunch box is excellent in the sealing between the lid and the container, it cannot be completely sealed, so the liquid juice from the side dish oozes out of the container during carrying, and other lunch containers It was easy to adhere to the packaging bag, etc., and when taking out the lunch container from the packaging bag, the liquid juice adhered to the hand, and there was a problem in terms of hygiene.

In order to solve the above problems, a lunch container shown in Patent Document 2 has been proposed. The lunch box is composed of a synthetic resin container main body and a lid, and the container main body has a plurality of food storage portions partitioned by a partition wall inside, and an inner upper portion of at least one specific food storage portion In addition, a protrusion formed so as to be inscribed in the food storage portion of the container main body formed on the lid body is configured to fit inside.

However, in the above lunch box, it is possible to prevent the juice from the sugar beet stored in the food container from adhering to other ingredients, but the juice is attached to the sugar beet stored in the food container. If the seasoning of sugar beet is thinned by the liquid juice or the attachment time of the liquid juice to the sugar beet is prolonged, the sugar bean will not be able to maintain the form during cooking and the appearance will deteriorate. have.
